Purely from a functional perspective.
No. You didn't even need new wheels--those tires would fit on the stock 17" wheels.
The only thing the lift kit will do for you (other than looks) is that maybe--maybe--the lower backspacing on the wheels likely puts the tires in a worse position vis-a-vis your fender flares when you flex offroad. Ie, on stock wheels the flex would've sent the tire up into the interior of the fender flare, but now it will send it into the lower outside edge.
So I suppose the right answer is likely that you didn't need new wheels or a lift, but once you got the wheels the lift was probably a good idea.
